I have had a 243 Win and 25-06 Rem Ruger No1 rifles. The accuracy was good for deer hunting but they were not good for long range shooting. But I did try working on the forarm hanger and free floating the barrel which helped a bit. I have read that by having some clearance between site rail and action improved the accuracy on some No 1s . Most gunsmiths can tune up bolt action rifles but may not be use to working on the No 1 Ruger.
